Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...
